FRANK B. McMAHON, or NEw YoRK, Y.-

STATTONARY non-snusn DEVIQEEOR wooL coMBEnsI To all whom it may concern:

Be it known'that I, FRANK B. McMAr-ioN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in-the county of Kings and- State of New York, have invented a new and.'use ful Improvement in Stationary Non-Brush Devices for WVool-(Jombers, of which the following is a specification. a 4 g This invention relates to an improvement in a stationary, nonbrush device adapted to press wool into the needles of a; circle combing machine such as is used in the combingof'wool.

One of the objects of the invention is to do away'with the dabbing brush and dabv device attached ,toflthe circle column and ,bing motion such asis used-on wool-combmg machines of th s character, whichuat- 'tachments are, as well known, generally ex,- pensive to keep in repair and somewhat complicated and difficult to adjust, and substitute therefor a device which is simple, easily adjusted, and which will wear'indefinitely.

A further object of the invention is to eliminate entirely the use of power in driving-a'dabbing motion, and substitute there;- for a device that \Vill1h0ld the wool'in'to the needles of the combing machine, but which of power. I e

. -Another object of the inventionisto avoid the uneven wearing of'a. bristle brush gen,- erally used on woolcombing machines, and the consequent uneven, work thereby pro.- duced and substitute a stationary, metal device that will not wear uneven in certain parts-but which will at all times operate evenly on the wool,consequently making an device does not haveto be driven by means l .even sliver coming from each side of. the

comb, thereby securingbetter and more 11111 form-work from the" machine, besidesincreasing the quantity of production. ff- 1 v Further objects of the invention are to provide a simple method'of quickly ad usting the device onthe-combing machine, and

quickly disconnecting it from the @machine forjmeans of repairing other; parts of the combing machine whenever necessary, and

toprovide a method of holding the blades in a pre-determined position centrally between the rows of needles or pins so that the blade cannot in any way-injure .thepinsbyshif-ting its position, butwhenever an. extraend' or piece of wool goes under the blades, the blade or blades are caused thereby to oscillate vertically only, so that injury to or breaking of the pins in the circleis avoided. .In the same way whenever the machine gets clogged or any foreign matter lodges inithe circles, thev extra matter raises the blade or blades onthe pistons andafter therforeign matter has passed. under, the blade or blades return to their original; positlons.

, The blade" or blades, therefore, adjustth'emse'lves Y automatically-to any thickness of the wool, orindeed to any foreignmatter presented to the blade or blades.

In theaccompanying drawings, which are to be taken as part of this specification and in which I haveshowna preferred form of the invention Y Figure 1 represents atop plan view of the showing the dotted lines indicating the rows "of needles or "pins inthe comb circles. Fig. 2 represents'a front view of the entire device,

Fig. represents a detail view, partly in section, showing one ofthe" pistons holding the blades. FigA represents one of, the sev eral radial arms, detached; ,and shows the chamber for the pistons ustreferred-to.

. I .The same reference characters indicatethe' same parts in all-the-figure's.

Referring-to the numerals on the ings there. is shown and. the invention con sists of a supporting "plate l', supporting a to the pistons 4 and}; held in proper position .by'the holder 2. -;The'holder and bladestogether are so'attached-to the column!) of the combing machine as to press the wool down into the pins of the comb circles with that degree oftension required by th e wo-rk to be done. vThis tensionis regulatediby the spring 6, in connection with theadjustable collarll lfand the piston 4, The dotted lines .7, indicate the-rows of. pins or needles on the comb" circles, and between which ,rowsof pins the blades .3: are. adjusted .toa pre-determined position.

The supporting plate.l.-has a, s lot by which the holder and'blades are adjusted to thepins, after whichthe plate is bolted to the-column .5 by the bolt 9, binding on the washer 10, and further secured from shifting by the two set screwsll."

drawplurality of adjustable radialarms 2, which 5 parts will be called the holder, {and a plu- 'rality of narrow blades 3, which are attached ment of the radial arms, piston chambers,

pistons, and theblades are preferably as shown in the drawing.

Each of the several radial arms contains as many pistons as is necessary to hold each of the blades by a plurality of pivot joints 17 located at the top of the blades. The

piston chambers 13 are formed by boring holes in the holders or radial arms 2, and through these holes or chambersthe pistons i are passed. The top of the piston is secured by a collar 1&, which has one or more sides round and the other opposite sides straight, and the position of the piston, and consequently the blades,-is adjusted to; any predetermined position by means of a set screw 15 passing through the collar 14 to the piston 4E, and a set pin 18, usually located opposite the set screws on the collar and set into the chamber walls, as shown in de: tail in Fig.3. By this method of fastening, the piston, and consequently the blades, can not turn, but can move only up and down in the chamber. The opposite end of the piston 4 is finished in a square shoulder 16, slotted to receive the: blade 3, which is fastened by a pivot 17, thereby making apivot jointbetween the blades and the piston. Moreover a spiral spring 6, is placed upon-the lower end; of the piston l,'bearing between the bottom of the holder 2 and the shoulder 16 on the end ofthe piston 4:, as is shown in Fig. I

The method of operating the device isjby adjusting the tension'of the spiral spring 6 by meansof the movable collar lt on the piston 4:. This determines the degree of tension required to be exerted by the blades 3,

' which have been first adjusted to the proper position centrally between the rows" of pins. Nhen properly-adjusted the bolts are tightened and the blades are held in this predetermined-position. No power is usedto drive the", device; the tension or pressure upon the Wool'being supplied by the proper positioning and adjustment of the entire device together with the adjustment of the collar on the piston and the tension of the spring. As the hank of wool approaches the nose of the blade 3 it is gradually and gently pressed down under the center of the blades where an even and gentle pressure is maintained by the blades while the wool is being combed by the tangent circles of pins or needles. This action of the device allows the wool, after passing a certain point, to gradually come up to the top of the needles after being combed, giving the drawing aprons a nice, free end to draw, which is an improvement over the old dabbing brush and the various devices for jabbing or compressing the wool far down into the needles.

Having thus described the invention, I claim as new anddesire to secure by Letters Patent,

1. In a device of the kind described, a supporting plate, having a slot therein for -means of adjustment, attached to the column of a Wool combing machine, a plurality of radial arms or holders, slotted for means of adjustment, and attached rigidly to the said supporting plate, a plurality of pistons passing through chambers in said holders and attached to narrow blades by slotted shoulders, and pivot joints, a plurality of narrow blades. attached to and held in proper positions centrally betweenthe rows of pins,a collar containing a set screw and a set pin, for means of adjustment, at one end of said pistons, a spring'on the ends of the pistons, for the purpose of. yielding and for acting upon the piston to bring it back to its original position when it becomes displaced, the construction of the holder and the arrangement of the radial arms and pistons being adapted to prevent any side or radial motion of the blades, thereby protecting the pins on the circles from harm.

2. In a wool combing machine, the combination of a supporting plate, a plurality of In testimony whereof I have aliixed my signature in the presence of two witnesses.
